Abstract

The utility model relates to a full-rotating centrifugal machine for medical examination. The full-rotating centrifugal machine comprises an inner bevel gear and a rotating ring which are arranged inside and outside respectively and are concentric, the rotating ring is driven by electric rotating shafts, a plurality of test tube clamping devices are mounted on the rotating ring by taking the central axis of the inner bevel gear as a center, each test tube clamping device comprises a cross shaft sleeve, a conical gear meshed with the inner bevel gear is arranged at a radially inward end of each rotating shaft, and a test tube orifice clamp sleeve is arranged at the end of a fixed cylinder. The rotating ring drives the test tube clamping devices to rotate in the direction of the central axis to obtain traditional centrifugal force, the test tube clamping devices can rotate in a single straight tube sleeve under driving of the cross shaft sleeves and the inner bevel gear, better separation effect and efficiency can be achieved without only increasing rotating speed by combining two driving forces, and the requirements of the centrifugal machine for the structural strength of parts and the rotating speed of a motor are lowered, so that manufacturing cost is reduced.
